productive soil can contain anywhere from 100 million to 1 billion individual bacteria
I've just been doing some research on this question and I found... "a teaspoon of rich garden soil can hold up to a billion bacteria, several yards of fungal filaments, several thousand protozoa and scores of nematodes"

Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.
Soil bacteria are not responsible for fixing nitrogen from the atmosphere. This process is carried out by nitrogen-fixing bacteria like Rhizobium and cyanobacteria.
There can be billions to trillions of bacteria in 1 gram of sandy soil, depending on various factors such as soil composition, moisture content, and nutrient availability. Bacteria play a crucial role in soil health and ecosystem functioning.
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.
A pinch of soil can contain billions to trillions of bacteria, depending on factors like soil type, location, and environmental conditions. It is estimated that a gram of soil can contain anywhere from 100 million to 1 billion bacteria.
Soil bacteria are not responsible for causing diseases in plants or animals. This role is typically played by pathogenic bacteria or other organisms.

The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
Decomposing bacteria and nitrogen-converting bacteria important to farmers because they help to send nutrients through the soil. These types of bacteria regulate nitrogen n the soil.
